Benefits of technology

[0017]If the device comprises a carrier with a foam material cap arranged thereon, in a further development the carrier is pivoted relative to the handle and features either a positive engagement element or a recess, in order to effect a locking of the carrier relative to the handle.
[0018]For reasons of improved handling ability, the handle can feature at least partially an angular cross-section or a round cross-section with a structured surface, so that the handle and the cell collection device can be rotated better and more easily. In connection with the conical and thus rotationally symmetrical device for cell collection, an angular handle, in particular in the embodiment as an angular rod, represents a particularly economical and easy-to-handle solution, with which the cell removal and the smear can be carried out very well. The angular rod enables or facilitates the application of the necessary torque during the rotating cell removal in the cervical canal. Because the removal device is completely surrounded by the cervical canal, the...

Problems solved by technology

During the sampling it is necessary to perform a rotary motion, since spatially limited conditions prevail in gynecological use; in particular the possible deg...

Embodiment Construction

[0030]FIG. 1 shows a device 10 for removing and smearing cells for a cytological examination with an angular handle 1, in this case hexagonal in cross-section, and with a device 2 tapering conically towards the front for the collection of cells. The device 2 features on its outer side 12 a layer of foam material to which cells attach during a cell removal, in particular during an early detection for cervical carcinoma. In the front area I the endocervical cells are collected, in the section P of the device 2 facing the handle 1, the cells of the portio surface are taken up. Due to the elastic foam material layer, the cell removal takes place in a manner that is gentle to the tissue and with a higher cell yield than with plastic brushes.

[0031]FIG. 2 shows a variant and further development of the device 10 according to the invention, with a handle 1 in which a carrier 3 in the form of a plastic rod is pivoted and can be pushed in the direction of the longitudinal extension 5 of the ha...

Abstract

A device for removing and smearing cells for a cytological examination with a handle at whose front end a device for the collection of the cells is arranged. The device provides an economical solution for cell collection and a reliable solution for smearing on a microscope slide. The device is embodied as a cone tapering towards the front in which a stabilizing device acting on a longitudinal extension of the cone is arranged.

Description

FIELD OF THE INVENTION[0001]The invention relates to a device for removing and smearing cells for a cytological examination with a handle at whose front end a device for the collection of the cells is arranged. In particular such a device is suitable for undertaking examinations of the cervix, in particular for taking a smear.DISCUSSION OF BACKGROUND INFORMATION[0002]Various methods of undertaking a cell smear are known from prior art, in particular during screening for cervical carcinomas. One method for the collection of the cells comprises the use of a cotton carrier in which cotton is arranged at one end of a strip of wood. Experience has shown that a slight lesion is caused by a cotton carrier, and moreover a deep endocervical cell removal is enabled. A disadvantage of the use of a cotton carrier is the fact that two cotton carriers are required for one smear and that as a rule the smearing pressure is uneven. Too strong a smearing pressure leads to considerable cell- and nucle...
